Aside from those unfortunate souls who have a dual-boot system that both wasn't detected by Microsoft and also is out of date enough so that its boot bits are noncompliant, who else might be affected by this?

Ventoy will fail to work on a Windows system with August's updates. The current Ventoy doesn't have a "shim,4" compliant EFI bootloader.

You can fix this if you don't care to wait for Ventoy to fix this.
Or do what probably a lot of people do, which is disable SecureBoot and forget to ever turn it back on again.
